What is Change-Point Analyzer?
Change-Point Analyzer is a shareware software package for analyzing time ordered data to determine whether a change has taken place. It detects multiple changes and provides both confidence levels and confidence intervals for each change. The results are clearly displayed in table form and supplemented by easy to interpret plots. It can be used with all types of data: pass/fail, individual values, averages, ranges, standard deviations, normal, nonnormal and ill-behaved data like bioburden and particulate counts. It can be used to trend complaints, inventory turns, sales, particulate counts and just about anything else.
Change-Point Analyzer is simple to use, even for someone with no experience with control charting. It can be learned in about 15 minutes by following the tutorials provided below. It automatically verifies assumptions, checks for outliers and guides the user in handling such special cases. It even comes with a Excel Add-In making it possible to perform the analysis directly from Excel. For those in FDA regulated industries, it comes complete with a validation package.
Change-Point Analyzer is an important problem solving tool which can be used to complement real-time control charts. Analyzing control charting data using Change-Point Analyzer will help to better isolate the time of a change, help to identify more subtle changes missed by the control chart, and expose false detections.
When performing a one-time analysis on historical data, a change-point analysis is preferred to control charting, especially when you are dealing with large data sets. When performing such analyses, a change-point analysis has numerous advantages over a control chart.
Change-Point Analyzer was developed by Dr. Wayne Taylor. It utilizes state of the art techniques including CUSUM charts and bootstrap analysis.
